A study was conducted to determine the wild service tree (Sorbus torminalis) seed source effects on seed emergence, seedling establishment, survival and growth from two locations. Twenty healthy mother trees were randomly selected at each location. Two hundreds seed per tree were planted in a nursery. Seed emergence and seedling longevity were recorded. Thirty seedlings of each selected mother trees were planted and 10 seedlings of each mother tree were randomly allocated. The effect of seed sources on seed emergence and seedling survival was significant (p less than 0.05) in nursery bed. Emergence rate from higher altitude seeds was greater than that at lower altitude. Seed source effect on seedling establishment and seedling growth was statistically significant. Seedlings showed better growth from lower altitude site than those from higher altitude.
